Differences in age-related effects on brain volume in Down syndrome as compared to Williams syndrome and typical development

Table 3 Brain regions where the relationship between age and volume was significantly different between participants with Down syndrome (DS) versus Williams syndrome (WS)

Region of interest	Group (DS versus WS) × Age Interaction Term
Region of interest	t	P-value	Difference in R²
Right lateral ventricle	4.42	8.64E-05	0.14
Left lateral ventricle	3.75	1.35E-04	0.12

The right lateral ventricle association was significant after Bonferroni correction.
